IPA: /ˌeɪ.kloʊrˈhaɪ.dri.ə/
KK: /əˌklɔːrˈhaɪdriə/
This term refers to a condition where there is no hydrochloric acid present in the stomach's digestive juices.
The patient was diagnosed with achlorhydria after tests showed no hydrochloric acid in his gastric secretions.
Achlorhydria is formed from "a-" (meaning without) and "chlorhydria" (from Greek "chloros" meaning green and "hydor" meaning water, referring to hydrochloric acid in the stomach). The term describes a condition characterized by the absence of hydrochloric acid in gastric secretions.
Think of 'a-' meaning 'without' and 'chlorhydria' referring to the 'green water' of stomach acid — achlorhydria means the absence of that stomach acid.
